Two long-range free kicks from Gareth Bale handed the Premier League outfit a 2-1 win at White Hart Lane last Thursday, with the French side grabbing a vital away goal thanks to Samuel Umtiti's stunning half-volley from the corner of the penalty area.

However, Sigurdsson has backed Tottenham to come out firing and put the tie to bed as soon as possible.

"We always look capable of scoring, especially away from home and we’ve done that in almost every game,” Sigurdsson told the club's official website.
